Question

3. Summarize one-carbon, two-carbon, three-carbon, four-carbon, five-carbon and six-carbon units or compounds which are important in human biochemistry.

Answer 1

Ansis * one carbon compound : C02carbon dioxide is the one carbon compound present in human blood as well as in other body parts in blood it plays an important role to maintain the blood PH. They also regulate the enzygnatic reaction in metabolism of b perticularly in Anaerobic respiration in human body, carbon dioxide * Two carbon compound 'Acetyl-COA : Acetyl-CoA is main precursor for citric acid cycle and it is the enol (CoAlucl of compound that reaut with Pyruvate means byruvate is converted into Acetyl-CoA in presence of pyruvate delpdrogenase compless. Acetyl-cot * Three carbon compound : Apravate : Pyruvate is the end product of glycolysis that further oxidised in presence of ccygen in mitochondria to form Acetyl.com 1 C= 0 0 -0 - 1 C= o 0- 3 CH3 Pyowate

Four carbon compound : Oxalcacetale : Oxaloacetate is an compound / chemical compound that form during citric and cycle and mainly orsed in Intermediate reusion of citric acid cycle: ie pyruvade to Aceryl Co-A and then Acetyl CoA no react with react with ox oxaloacetate to form citrate by sohalensation reaction 0=c-CoO 2 CH2 -"C00 oxgloacetate # five carbon compound : Diacylglycerol. It is five carbon compound present in human body and that are used for lipid metabolism from glycerol - 3-phosphate to tracylglycerol *CH 2-0-4 FRA 2 CH - o - 8, 3 CH2 – OH Diacylglycero) * SIX carbon compouna : Glucose ! pucase is monosacharide containe, ci Cembon atom · which us noain precursor for glycolysis metabolism and in human body used as eshergy molecule. Glucose maintain the blood sugar level. It alo participate in many metabolic pathways in human body. I CHO 4 - - 01 Hondent 1-4-0H H-LE OH 16 CH₂OH Glucose
